I found two larder beetles in my husbands drawer over the weekend. Cleaned all the clothes and bed?

... stuff in hot water and dried on hot heat. I vacuumed up the whole room.

The next day I found 1 carpet beetle hanging on a drape in my living room. Flushed it and then vacuumed the entire house.

Today I found 1 larder beetle sitting on top of a piece of paper towel in the trash can. Again flushed it.

All coincidence and they are flying into my house or do I have an infestation? Not seeing any larvae or any large groups of them
